Sleep and insomnia symptoms in adolescence
Vi spenderar en tredjedel av våra liv sovandes och sömn är en avgörande faktor för god hälsa och välbefinnande. Men det är även viktigt att erkänna sömnens komplexitet, eftersom det är flera faktorer som kan påverka sömnen. Både biologiska, kontextuella och psykosociala faktorer har inverkan på ungdomarnas sömn. Otillräcklig sömn, sömnproblem och symptom på insomni är vanligt hos ungdomar. SömnlösInsufficient sleep, sleep problems and insomnia are common in adolescents, and insomnia and insufficient sleep are public health concerns that can impact adolescents’ mental and physical health. There are several different treatments for sleep problems and insomnia, and there is a great focus on the problem when it has already arisen. However, since this is a public health problem, it is important
Advanced Remote Sensing Precipitation Input for Improved Runoff Simulation : Local to regional scale modelling
Accurate precipitation data are crucial for hydrological modelling and rainwater runoff management. Precipitation variability exists through a wide range of spatial and temporal scales and cannot be captured well using sparse rain gauge networks. This limitation is further emphasised for urban and mountainous catchments, especially under global warming, causing an increased frequency of extreme ev
Patronage effects of off-peak service improvements in regional public transport
The purpose of this study is to look into patronage effects of extended supply outside peak hours on regional public transport services. Previous studies have shown that the service frequency is an attribute of great importance for regional passengers, but little is known about the details regarding peak and off-peak frequencies or service hours. The present study addresses this knowledge gap, dep
Comparative immunomodulatory effects in mice and in human dendritic cells of five bacterial strains selected for biocontrol of leafy green vegetables
The market for ready-to eat vegetables is increasing, but unfortunately so do the numbers of food-borne illness outbreaks related to these products. A previous study has identified bacterial strains suitable for biocontrol of leafy green vegetables to reduce the exposure to pathogens in these products. As a tentative safety evaluation, five selected strains (Rhodococcus cerastii MR5x, Bacillus coa

Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies
The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. This second fuel can be a low carbon or renewable high-octane fuel, that otherwise could not be applied in a diesel engine. Good results on emissions and effici
The ESS neutrino super-beam near detector
The ESS Neutrino Super-Beam (ESSnuSB) is a proposed long-baseline neutrino oscillation experiment, performed with a high-intensity neutrino beam, to be developed as an extension to the European Spallation Source proton linac currently under construction in Lund, Sweden. The neutrinos would be detected with the near and far detectors of the experiment, the former within several hundred meters of th
Ventricular longitudinal function by cardiovascular magnetic resonance predicts cardiovascular morbidity in HFrEF patients
Aims: Ventricular longitudinal function measured as basal-apical atrioventricular plane displacement (AVPD) or global longitudinal strain (GLS) is a potent predictor of mortality and could potentially be a predictor of heart failure-associated morbidity. We hypothesized that low AVPD and GLS are associated with the combined endpoint of cardiovascular mortality and heart failure-associated morbidit
Characteristics and outcomes in patients with atrial fibrillation and acute coronary syndrome treated with ticagrelor and novel oral anticoagulants
Introduction: Optimal antithrombotic treatment after an acute coronary syndrome (ACS) in patients with atrial fibrillation is unclear. Data on outcomes in patients on concomitant ticagrelor and the novel oral anticoagulants (NOAC) is scarce. This study therefore sought to describe patient characteristics and treatment outcomes in patients with atrial fibrillation and ACS treated with concomitant t

Symmetry in Asymmetric Catalysis and Hydrogen Bond-Based Self-Assembly : Synthesis and Investigations
The thesis elaborates on four different projects focusing on synthesizing symmetry-related molecules and investigating their performance as catalysts for asymmetric catalysis or as monomers for hydrogen bond-based self-assembly.Chapter 2 describes a new method to desymmetrize a meso-ligand. Two pseudo-Cs-symmetric bissalen complexes from a meso bissalen ligand and two different pairs of metal ions
Cross-borehole electrical monitoring in groundwater remediation projects : understanding the flow path of remediation agents
In-situ remediation of contaminated groundwater often relies on the installation of a treatment zone degrading the pollution plume. In such projects, adequate delivery of remediation agents in the whole target volume is not trivial. Monitoring the spatial distribution of injected reagents is important for engineers and decision-makers, in order to determine the need of more careful injection in so
Transport in nanowire-based quantum dot systems: Heating electrons and confining holes
Quantum dots embedded in an electronic circuit allow precise control over the charge transport behaviour of the system: Charge carriers can be individually trapped or precisely shuffled between a series of quantum dots in a strictly sequential manner. This introduces ideal conditions to study fundamental quantum physics and such devices are in the focus of extensive efforts to develop quantum info

Attitudes towards HPV vaccination in Sweden: a survey study
Background: While HPV vaccination uptake in Sweden is quite high, at around 80%, vaccine hesitancy remains an issue in countries throughout Europe. The latter can be related to a contemporary context of increased contestation of expert knowledge and of a large share of information on health-related issues including vaccination today being sought via the internet. Still, there is a paucity of recen
Size-based isolation and detection of renal carcinoma cells from whole blood
Renal cell carcinoma (RCC) is a tumour type with an indolent growth pattern and rather vague symptoms. The present study developed a platform for liquid biopsy of RCC based upon the isolation of circulating tumour cells (CTCs). Founded on the observation that RCC tumour cells are considerably larger than leucocytes, the present study employed a microfluidics-based system for isolation of RCC CTCs
